Load-Force-Weight
Applications

When
forces acting on mechanical constructions are measured,
the additional equipment required can often be costly
and difficult to install. Magtrol's Load Measuring Pins offers
an excellent solution since they acts as a direct element
in the assembly, replacing a non-instrumented pin or shaft.

Magtrol SA developed a specially designed Load Measuring
Pin for a German company that provides the world's leading
aerospace OEM manufacturers and air-cargo operators
with the most advanced, efficient and cost-effective
onboard cargo and baggage-handling systems.

The customer was in need of a measuring device that
would monitor the weight of air-freight transported
by conveyor belt. The load measuring device needed to
be comprised of specific aerospace requirements including
first article inspection, COC, 3.1B Material Certificate
and a special aerospace marking. The customer also had
specific price, design, quality and delivery expectations
which Magtrol was able to meet by modifying the existing
LB 210 Load Measuring Pin, without sacrificing reliability.

Measuring Loads
on a Container Loading Bridge

Pin in place of shaft for accurate load monitoring, load
balancing and overload protection.

Using load pins to measure loads on a container loading
bridge is a typical application for Magtrol's Load Measuring
Pins. This specific example shows how simple it is to
replace existing shafts with load measuring pins just
by slightly transforming the fixing system.

Four Magtrol Load Measuring Pins are located in the
lifting rope attachments as indicated in the diagram.
Knowledge of the pulley configuration allows one to
work out the weight of the container held by the quick
clamping device.

The LE Series Load Measuring Pin is ideally adapted
to this type of assembly, being equipped with the 4
to 20 mA electronic unit. This enables a direct connection
to the PLCs or a display in the driver's cabin, even
if the cabin is remotely located. The PLC of the crane
will provide simultaneous monitoring of both the corner
loads and total loads of a container to provide overload
control and warn of shifting or unbalanced loads.

Harbor Crane Protection

Magtrol's LB Load Measuring Pins are
commonly utilized in harbor cranes to provide load acquisition
of all crane positions. The pins simply replace the roller
shafts in the pulley system making for low cost installation.
They provide simultaneous monitoring of corner and total
crane loads with high repeatability and high accuracy.
With quality direct load measuring along with protection
against overload, the user is given the vital information
needed to prevent crane accidents.
